Earth-9

The interference of the original Atom causes the Cuban Missle Crisis to escalate into a limited nuclear exchange that results in the nuclear obliteration of Florida and Cuba. The aftermath of the destruction of Florida shapes the lives of several characters. The city of New Atlantis is created out of the remains of the city of Atlanta and is later the birth place of the Joker. A group of sea creatures are mutated by the radioactive fallout into humanoid form and become known as the Sea Devils. The other major event to have repercussions is the Soviet Union's invasion of Czechoslovakia in 1968, which leads to the creation of the Manhunter. The Soviet Union still exists into the late nineties and is still a world superpower.
